MC10H189FN

Overview

The MC10H189FN is a Hex Inverter with Enable manufactured by onsemi, housed in a 20-PLCC package. It operates within a supply voltage range of -4.94V to -5.46V and supports an operating temperature from 0°C to +75°C. The device features a typical propagation delay of 1.3 ns for data-to-output transitions and 1.8 ns for enable control. Power dissipation is typically 180 mW per package under no-load conditions.

Feature Summary

• Provides hex inverting functionality when the common enable input is held low.
• Forces all outputs to a low state when the enable input is high.
• Offers improved noise margins over standard MECL 10K family parts.

Applications

• High-speed digital logic inversion
• MECL 10K compatible system design
• Enable-controlled signal routing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead-free status. Confirm RoHS compliance requirements as standard packages may differ from Pb-Free variants. Check current product lifecycle status as obsolescence notices may affect long-term availability.

Selection Notes

Select this component for applications requiring MECL 10H speed improvements without increased power consumption compared to the MECL 10K family. Ensure the design accommodates the required negative supply voltage and differential output termination. Verify that the 20-PLCC footprint matches the target PCB layout constraints.

Part Context

This part belongs to the MECL 10H series, designed as a functional and pinout-compatible replacement for the standard MECL 10K family. It delivers a 100% improvement in propagation delay while maintaining similar power-supply current levels. The series targets high-speed digital applications requiring reliable ECL performance.
